Mark Iv Vs A7v

The German A7V and the British Mark IV were similar in weight, size, and speed, but differed significantly in armour, armament and maneuverability. The A7V had thicker armour, and had nearly double the horsepower per ton. The Mark IV's pair of side-mounted 6pdr cannons forced the vehicle to present its side arc to an enemy in order to fire one of its main guns. Possessing twice as many machine guns as the Mark IV, the A7V had a frontally mounted 57mm gun that proved capable of defeating the Mark IV's armour. The Mark IV's rhomboid design proved superior in crossing trenches, climbing obstacles and moving over rough terrain. As the first tank-versus-tank engagement in history, the fighting around Villers-Bretonneux showcased the British Mark IV and German A7V designs. Although not purpose-built to combat enemy armour, both vehicles proved the viability of such operations, which during the postwar period led to key advances in suspension, armour, gunsights, ammunition, and command and control. While the British continued to develop their armoured forces, German armour development never materialized, and only in the postwar period did they address the issue.

This book draws us into the dangerous world braved by American and North Vietnamese airmen in the skies over Vietnam. Influential leaders and tacticians are profiled to provide a comparative evaluation of their contrasting skills. This book also reveals the technical specifications of each jet with an analysis of the weaponry, avionics and survival devices of the F-4 Phantom II as flown by the USAF and the MiG-21. The fighters' strengths and weaknesses are also compared, including turn radius, performance at altitude, range and structural integrity. First-person extracts reflect on the dangers of these aerial duels, as USAF pilots and their counterparts struggled to overcome each plane's shortcomings.

The 1914-18 war has been referred to as the 'chemists' war' and to commemorate the centenary this collection of essays will examine various facets of the role of chemistry in the First World War. Written by an experienced science writer, this will be of interest to scientists and historians with an interest in this technologically challenging time.

This title looks at the Medium Mark A Whippet, one of the most successful British tanks of World War I and, when placed alongside existing titles covering the Mark I, Mark IV and Mark V, completes the New Vanguard series' coverage of the major British tanks of the war. The evolution of the Whippet is examined in detail, from design and development to mechanical details and crew duties, and information on the operational use of the vehicle is drawn from war diaries and battalion records. The Whippet was involved in several well-known incidents that will be presented in this volume, including the clash at Cachy on April 24, 1918, the actions of the 6th Battalion tank known as “Musical Box” on August 8, 1918, and Sewell's Victoria Cross-winning exploits with the 3rd Battalion on August 29, 1918. Mention will also be made of the Whippet's involvement with the Tank Corps' expedition to Russia. In addition to this examination of the Mark A Whippet is a study of the other Medium tanks up to the end of the war: the Medium B, Medium C, Medium D and the experimental American Studebaker tank.

In the Age of Fighting Sail (1650–1820), ambitious officers of the navies of many nations sought command of a frigate. Speedy, nimble and formidably armed, frigates often operated independently, unlike the larger ships of the line. Legendary sailors such as Edward Pellew and Charles-Alexandre Léon Durand, Comte de Linoise, found that commanding such a ship offered numerous opportunities for wealth. In this book, four representative frigate duels are examined: first, a battle fought between two closely matched ships (HMS Nymphe (36) vs La Cléopâtre (32); second, a victory won by an inferior British frigate over a superior French frigate (HMS Pallas (32) vs Minerve (40); third, a victory – the only one – by an inferior French frigate over a superior British frigate (HMS Ambuscade (32) vs Baïonnaise (24), and fourth, victory of a superior British frigate over an inferior French frigate (HMS Indefatigable (44) of Hornblower fame vs La Virginie (40). Featuring specially commissioned artwork and offering expert analysis, this study provides a vivid account of the bloody combats fought by the most romantic warship of the Revolutionary and Napoleonic era – the frigate.

The First World War's fierce battles saw the need to develop military technology beyond anything previously imagined: as exposed infantry and cavalry were mowed down by relentless machine-gun attacks, so tanks were developed. Here author Craig Moore presents every First World War tank, from the prototype 'Little Willie', through the French heavy tanks to the German light tank. He gives a focused history of the development of this game-changing vehicle and the engagements it was used in – vital battles such as the Somme and Cambrai. Stunningly illustrated in full colour throughout, Tank Hunter: World War One provides historical background, facts and figures for each First World War tank as well as the locations of any surviving examples, giving you the opportunity to become a Tank Hunter yourself.

The RAF introduced the Avro Lancaster in 1942 and used it to spearhead this aerial offensive. In response, the Luftwaffe created an elite nightfighter force based primarily upon the Bf 110. The Luftwaffe was quick to equip it with airborne radar that allowed it to intercept and destroy Lancasters over Germany. In turn, the RAF adopted countermeasures such as the Monica rearward-looking radar to alert Lancaster crews to the approach of nightfighters. In May 1943 the Luftwaffe suddenly developed a novel technical and tactical approach to attacking RAF bombers. The new tactic proved amazingly successful, and British bombers could be attacked from below with no warning. For its part, the RAF failed to detect the new German tactic for six crucial months, during which time its Lancaster bombers were almost defenceless against this new threat. In time, however, the German advantage of surprise was lost and the RAF developed countermeasures to deal with the new threat. The duel between upgraded Bf 110s and Lancasters in the night skies over Germany became increasingly dominated by cutting-edge technology, which would determine the efficacy of strategic bombing.
